Which of the following are steps in creating a work plan?

The correct choice outlines an essential step in the process of creating a work plan. Adding activities to the shift is crucial because it defines what tasks or responsibilities will be assigned to employees during their scheduled hours. Activities can include things like customer service tasks, meetings, or breaks, and they ensure that shifts are efficiently planned and that staff are allocated to tasks that meet operational demands.

Setting up this structure helps to ensure that every shift is utilized effectively, supporting both employee workflow and organizational goals. Without clearly defined activities, staffing could lead to inefficiencies, gaps in service, or overwhelming workloads on certain employees.

In contrast, the other options suggest approaches that would not yield an effective work plan. Validating the work plan only after it's been created neglects the importance of ongoing assessment and adjustments that should occur throughout the planning process. Skipping the weekly configuration setup compromises the foundational elements necessary for a coherent plan, and creating a work plan without assigning agents overlooks a critical component of workforce management, which is aligning the right personnel with the planned activities.
